Chapter 52: Solution
Zheng Ze was, after all, a university professor, so his reaction was slightly quicker. But as he arrived at the conclusion, his expression became just as shocked as Ye Gaoyi's, filled with disbelief.
With a slight tremor in his voice, Zheng Ze spoke, "Li Xuan... left from the airport."
Dong Yang was taken aback for a moment and immediately retorted, "How is that possible?"
"If he wanted to pass through security checks, he would need to undergo facial recognition. How could he have left from the airport..."
However, his voice grew softer, and he also realized something. This was the Jinglin Aerospace University. All seven members of the task force now understood the magnitude of their mistake.
"In the dark under light." They had diverted their attention from Li Xuan's presence at the university, neglecting this crucial clue. This was Jinglin Aerospace University! Li Xuan's choice of this institution was not a coincidence.
Not a train station, not a bus terminal, but an airport! It was an option they had previously ruled out. An option that should not even exist in their minds.
Indeed, as a passenger, he would undergo facial recognition, but what if he were a pilot? Turning the impossible into the possible—this was Li Xuan!
As they remained shocked and speechless, the administrator had already retrieved the books Li Xuan had borrowed and placed them one by one on the table in front of them.
Ye Gaoyi snapped out of his daze and began to flip through the books one by one. "University Physics" contained content about "Principles of Flight"... "Advanced Mathematics" covered "Cockpit Resource Management"... and so on.
Li Xuan, after entering the university, had studied books unrelated to aeronautics such as "Principles of Flight," "Air Navigation," "Cockpit Resource Management," "Human Factors in Flight," and "Aviation Meteorology."
